Booming Atrium Forest

Imitative-onomatopoeic origin — present-participle of boom, sharing root with Dutch bommen. As a color modifier, booming implies a saturated-and-loud-and-confident quality where the hue announces itself with full visual amplitude. Sits at the bold-and-resonant end of the grid, parallel to resounding and thunderous.

Latin atrium, Roman-house-courtyard. As a color modifier, atrium implies a Roman-and-modern-courtyard-with-skylight quality, the visual register of Roman-Pompeii-and-modern-Mid-Century-Modern-atrium hand-built central-courtyard-with-skylight atrium-and-impluvium-and-courtyard architectural surfaces under Roman-and-Mid-Century-Modern atrium-skylight light. Sits at the modifier-and-architecture end of the grid, parallel to loggia and quad in usage.

The dense canopy of a temperate or tropical woodland — oak, beech, pine, eucalyptus, mahogany — wherever leaves close above to filter the light below. Forest green refers to the average reflectance of a healthy mid-summer canopy seen from below: a saturated, slightly muted green with the matte finish of layered chlorophyll. Deeper than fern, cooler than olive, with the ecological weight of a word that has named every wooded biome on Earth.
